Configuring Route Map – RIP

iS5Com URM (Unified Route Map) is a portable implementation of the route map capability for IPv4 and IPv6 unicast routing software. The URM provides a single interface for the administrator to set up and manage route maps. It also provides a common unified method for routing protocols and static route management software to use route maps for different purposes. The independent nature of the implementation helps to avoid the duplication of the route maps in the different routing modules in a router.
